AUTOMATIC DELINEATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 512,089, dated January2, 1894.

Application filed April 12, 1893- Serial No. 470,089. (No model.)

To all whom it may concern.-

Be it known that I, FRED BANGERTER, a citizen of Switzerland, residinginthe city and county of San Francisco, State of California,

have invented an Improvement in Automatic \Vriting and Drawing Machines;and I hereby declare the following to be a full, clear, and exactdescription of the same.

My invention relates to a device for automatically drawing figures, orwriting, engraving, or delineating upon metals and similar work.

It consists of an arm by which the drawing or engraving tool is carried,and a mechanism by which said arm is actuated so as to describe thedesired letters or figures.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure 1 is an elevation of the rear of my device.Fig.2 is an end view of the oscillating block and its connections.

The object of my invention is to provide a mechanism by which statedfigures can be marked, written, drawn, or engraved, and it 2 5 may beused either to make letters, draw figures, or to engrave upon surfaces,such as watch cases, the.

In carrying out my invention I employ a lever arm A to which the pencil,pen or en- 0 gravlng or other tool is attached in such a manner as tomove over the surface B beneath the point of the tool, or the tool maybe stationary and the surface movable, the result being the same. Thisarm is fulcrumed 3 5 to a second lever arm C so that the end opposltethe one carrying the tool, projects alittle beyond the arm C. The arm 0is fulcrumed as shown at D to an oscillating support herelna fterdescribed, and the end of the arm C WlllCh projects beyond the fulcrumis connected bya rod E with a lever-F which is actuated by a cam G ashereinafter described.

From the lower end of the lever A a rod H connects with one of the bellcrank levers I, 5 one arm of which is fulcrumed to the stationary plateas shown at J. The other arm of the lever I is connected by a rod K witha lever actuated by a second cam L mounted upon the same shaft as thecam G. The fulcrum pin D of the lever C is fixed to a block M which isjournaled at each end in a yoke attached to the main support, and theblock M and lever C are caused to rotate slightly about the journal pinsby means of a lever N engaging an arm 0 which connects with thisoscillating block. The lever N is connected with a rod P which extendsto a lever Q, and this lever is actuated by a third cam R. These camsare all mounted upon a single shaft S, and upon the same shaft is fixeda gear wheel T which is engaged by a worm U upon the shaft V, so thatwhen the shaft is turned by a crank or any other well known and suitablemeans the gear and the cam wheels, before described, will be rotated 6 5simultaneously. The shaft may be turned by hand or by any mechanicalpower which may be found desirable. The first described lever 0 actsupon the arm A to move it up and down about the fulcrum point'of C.

. The bell crank lever I, connected with the lower end of the arm A,acts to move it in lines at right angles with the movements given by thelever C, and in the same plane, while the lever P acting upon the rotaryoscillating block M, gives the lever C a slightly rotary motiontransversely with the other two movements.

The surface B upon which the lines are to be formed is fixed parallelwith the arm A and at such a distance therefrom that the tool orimplement carried by this arm will move over and in contact with thesurface when impelled by the levers C and I to produce the two firstdescribed movements; but when the rotary motion of the oscillating blockis produced, it lifts the arm A away from the surface and allows it tobe moved by the first two levers out of contact with the surface to thepoint where it is desired to 0 again commence work, when the movement ofthe oscillating block again turns the arm A so as to bring the implementin contact with the surface. By the combination of these three movementsI am enabled to de- 5 scribe any desired pre-arranged figures by cuttingthe cams L, G and R with such irregular depressions and elevations aswill act upon the levers to which the rods E, K and P are connected, sothat these rods will be moved :00 independently, and in conjunction, toproduce the various figures.

It will be manifest that the particular arrangement of levers may bevaried without changing the relative movements uponwhich the inventiondepends, and for engraving, the surface to be engraved may be-connectedwith the moving parts, and the tool remain stationary.

For engraving purposes the parts should be made quite stifi and strongso as to exert a sutficient pressure upon the tool or surface to producethe desired cut,but for lighter work, such as drawing, making lettersand figures, the parts may be proportionately lighter.

a is a spring connected with the lower end of the lever A, so that whenthis lever has been moved in one direction by the action of the cam L,the spring will retract it when a depression in the cam allows the pointto descend. A second spring I) connected with a lever O in like mannerreturns that after it has been forced to make a movement by the cam, anda third spring 0 acts upon the oscillating block M to return that to itsposition after any rotary movement produced upon it by its cam.

It will be manifest that any figures, letter, form or design ofengraving, or other marking, may be executed by this mechanism, thedifference in the forms described depending upon the manner in which thecams are out.

In the present case I have shown the mechanism adapted to be concealedin the figure of a doll or automaton, the pencil or implement beingcarried in the hand of the figure, which is thus represented as doingthe work.

Having thus described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is-- 1. A delineating machine consisting ofthe movable tool carrying arm, a lever to which said arm is fulcrumed,an oscillating block upon which the second arm is fulcrumed, a bellcrank lever having one arm connected with the end of the tool carryinglever, and the other connected with a cam actuated point, a connectionbetween the rear end of the second lever and a second .cam actuatedpoint, and a connection between the oscillating fulcrum block and athird cam actuated point, whereby each of the lovers and the fulcrum arecaused to act independently and in unison, substantially as hereindescribed.

2. A device for delineating upon surfaces consisting of a tool carryingarm, a second arm C to which the tool carrying arm is fulcrumed, a bellcrank lever and arod by which one arm of said lever is connected withthe tool carrying arm, an oscillating fulcrum block to which the arm 0is fulcrumed, cams G,Land R fixed to a common shaft by which they arerotated and having irregular elevations and depressions, lever armsfulcrumed with relation to said cams and having projecting pointsadapted to engage the elevations and depressions upon their peripheriesand rods connecting said levers with the lever 0, bell crank lever andthe oscillating fulcrum block, substantially as herein described.

3. In a machine for delineating upon surfaces, the oscillating block towhich the lever C is fulcrumed having an arm 0 projecting at rightangles with the direction of the lever O, a cam R having irregularelevations and depressions upon its periphery, a lever arm having apoint adapted to engage said levers and depressions, and a rod extendingfrom said lever arm and actuated thereby having an end adapted to engagethe lever 0 whereby the fulcrum block is oscillated and the lever 0 andits connections tilted transversely to its line of movement about thefulcrum, substantially as herein described.

4- A machine for delineating upon surfaces, consisting of a delineatingimplement and a surface to be inscribed movable with relation to eachother in consonance with the lines to -be produced, a mechanismconsistingof ase- In witness whereof I have hereunto set my hand.
